International investigators are reviewing eight relevant areas for the completion of the final report on the mysterious disappearance of Malaysia Airlines Flight MH370. But, the next-of-kin of those on board missing Boeing 777-200 said the second interim report, which was released Tuesday, lacked details on the recent findings of potential debris on Réunion Island and Mozambique.

Authorities confirmed in the statement that the wreckage of missing Flight MH370 has still not been found despite a multimillion-dollar search in a remote part of the southern Indian Ocean. The three-page statement, which was made accessible to close relatives of those on board the jet prior to the report's public release, barely shed any light on the flaperon found on Reunion Island last July and the possible plane debris discovered in Mozambique last month, Channel News Asia reported.

The report stated that an independent international Air Accident Investigation Team, known as “The Malaysian ICAO Annex 13 Safety Investigation Team for MH370,” which was formed on April 25, 2014, is working “towards finalizing its analysis, findings/conclusions and safety recommendations on eight relevant areas associated with the disappearance of flight MH370 based on available information.”

The eight areas, according to the report, include analysis of the plane’s diversion from filed flight plan route, air traffic services operations during the time of the flight, profile verification of flight crew, and scrutiny of airworthiness and maintenance and aircraft systems.

The team will also analyze satellite communications, organization and management information of the Department of Civil Aviation (DCA), Malaysia and Malaysia Airlines. The review of wreckage and impact information will take place after the recovery and verification of a flaperon from the aircraft, the report stated, adding that the aircraft cargo consignment on board the jet will also be scrutinized.

“New information that may become available before the completion of the Final Report may alter these analysis, findings/conclusions and safety recommendations,” the report stated. The team of investigators will complete a final report “in the event wreckage of the aircraft is located or the search for the wreckage is terminated, whichever is the earlier.”

So far, the first and only piece of physical evidence to be recovered from the missing plane is a flaperon that washed ashore on France’s Réunion Island in the Indian Ocean — about 2,300 miles away from the current search area — in July 2015.

However, investigators are currently looking into debris found last weekend in the southeast African nation of Mozambique, believed to be from a Boeing 777 plane, the same type as Flight MH370. But, authorities are yet to confirm the 3.3-foot piece of metal’s links to the missing jet.
